VABNISH-REMOVER COMPOSITION. I

No Drawing.

To all whom it may concern:

Be it known thitfii- ALFRED SHETZLEY, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented a certain new and useful Varnish-Remover Composition, of whichthe following is a specificatlon.

This invention relates to varnish removers and more particularly to acomposition for this purpose that is harmless, odorless, efficient and anon-explosive. The remover is best adapted for use on interior woodwork,such as floors, trim and furniture, and does not require neutralizing ofthe treated surface before re-varnishing.

The varnish remover is cheap to manufacture, clean and safe in use andwill not clog a sponge or steel-wool and it can be removed withoutscraping.

The varnish remover is put up for the market in dry powder form inpackages ready for instant use by merely adding boiling water sufiicientto dissolve.

The invention consists in the following in gradients, combined insubstantially the proportions stated, viz; sodium percarbonate, 98parts; sodium peroxide, 1 parts: water, sufficient to dissolve.

The sodium percarbonate and sodium peroxide are mixed thoroughly, in theproportion stated, in an ordinary rotary mixer, or

otherwise, and then the boiling water, sufficient to thoroughly disolvethe mixture. is added. I prefer to prepare one pound of Applicationfiled December 12, 1924. Serial No. 755,558.

the chemical compound and to dissolve the same in 1% gallons of boilingwater, as the sodium peroxide modifies and improves the action of thesodium percarbonate, checking detrimental action of the caustic sodaformed after decomposition of the per salts. The boiling water impartsheat to the compound and renders solvent the varnish film. A furtherfunction of the sodium peroxide is its action as a bleaching agent uponthe wood, preventing discoloration after removal of the varnish. Thisproportion of boiling Water and compound will give excellent results.

The mixture is now ready for instant application and while hot it isapplied with a brush, broom, mop or sponge to the varnished surface.This application renders the varnish solvent so that at the expirationof about 20 minutes it can be readily removed or sponged off with anordinary sponge or steel-wool and tepid water without a trace of thesticky, gummy mess encountered through the use of ordinary re movers.

What is claimed is A liquid varnish remover composed of sodiumpercarhonate in the proportion of 98 parts, sgiummeroxidein theproportion of 1 parts, dissolved in boilin water. In testimony that Iclaim the foregoing as my own I have hereto aflixed my signature.
